[QUOTE="Toolsplusmore, post: 16002762, member: 154243"] I have both noise supressors unplugged and have verified they are not grounded out. I will check pin 55 of the PCM for voltage as well as checking ground on pins 3 & 25. I was under the impression that the PCM relay is in the CCRM when that is removed the fuse no longer blows and the power probe switches from short to ground to open circuit. The same thing happens when you leave the CCRM in and remove the actual PCM. I will check pins 8 and 10 on the CCRM and see if they are grounded to the battery negative. I will report back my findings this afternoon when I get home from work. Dave, what are you suggesting I try when you said "If fuse 26 is blowing, pull all the lines from the output side of the PCM relay." Thanks for all the help so far I still am puzzled but hopefully will get it resolved. [/QUOTE]
